dc.description.abstractThe brine produced by desalination poses a threat to marine ecosystems because of its high salinity and chemical composition. Hybrid processes and the integration of renewable energies such as solar and wind power are used to optimize the transformation of brine into valuable products, while minimizing environmental degradation. Our project aims to develop a comprehensive mathematical model for the conversion of reverse osmosis brine into hydrochloric acid and hydrogen using PV-electrolysis. The model is validated experimentally and used to optimize the system through a parametric analysis. The obtained preliminary results with conventional power supply demonstrated a high correlation coefficient of 0.995 and also a high determination coefficient of 0.992, suggesting that the simulation model is highly accurate and reliable. The integration of the photovoltaic power supply and the study of the effects of cell temperature, global radiation and electrolyte concentration provided valuable information on system behavior under different conditions. It was found that ambient temperature is optimal for the performance of the membrane electrolyzer supplied by PV, while the highest performance was obtained with high values of solar radiation of 900 W/m². Regarding the concentration of the electrolyte, a concentration factor of 5 conducted to the highest the conductivity, making the electrolyte becomes richer in ions, thus lowering the resistance of the electrolyte and therefore the ohmic resistance in the electrolytic cell.
